The method used was not portable. However, the underlying problem
still exists: the uc_locale_language used by libunistring does not
work with thread-specific locale_t locales.
* libguile/i18n.c (locale_language): avoid unpacking semi-opaque type
locale_t.
* test-suite/tests/i18n.test: set Turkish string and char locale upcase
and downcase tests to throw untested
Strings returned by nl-langinfo were always being encoded using the
global setlocale and not the scm_t_locale passed to the function.
* libguile/i18n.c (scm_nl_langinfo): fix encoding of strings
Libunistring uses a function uc_locale_language to extract the
current language from the locale information. It does this by calling
setlocale. This makes incompatible with Guile functions that use the
locale_t thread-specific locale API, because the values returned by the
call to setlocale ignore the locale set by uselocale.
As a workaround, this patch extracts the language from the locale_t
structure's __names field.
A more complete solution is needed. Perhaps that solution would test
that the __names field exists in the configure step and revert to
!USE_GNU_LOCALE_API in that case.
* libguile/i18n.c (locale_language): new function that performs the
same job as uc_locale_language but is compatible with uselocale

with locale_language

(scm_string_locale_upcase): use the scm_t_uint32 type for buffers
that are used primarily for libunistring and not for Guile strings.

for UCS-4 characters.

the new scheme strings.
* libguile/i18n.c (RUN_IN_LOCALE_SECTION) [USE_GNU_LOCALE_API]: new
macro for this define. Should work the same as the !USE_GNU_LOCAL_API
version

compare_u32_strings and compare_u32_strings_ci

functions
* libguile/i18n.c (str_upcase, str_downcase, scm_char_locale_downcase,
scm_char_locale_upcase): Cast chars to `int' when invoking `toupper ()'
et al. to avoid "array subscript has type 'char'" on NetBSD.
